Job Scheduling Simulator for Assisting the Mapping Configuration Between Queue and Computing Nodes.

In computer centers responsible for providing users with high-performance computing resources such as computer clusters, job throughput is an important criterion in satisfying users’ computing needs. The setting and configuration parameters in a job scheduler affect the criterion. In particular, the mapping between queues deployed in the job scheduler and computing nodes is highly related to job throughput. In most cases, however, the mapping configuration is conducted based on the administrators’ experience and knowhow partly because the tools that facilitate the determination of the mapping are not available. In this paper, we propose a job scheduling simulator that allows the administrators to investigate how the mapping affects job throughput. In the evaluation, the behavior of the proposed job scheduling simulator is assessed through a comparison with an actual computer cluster. In addition, real cases using the proposed job scheduling simulator are discussed.
